INSIDE TRUNK-BRACE.

SPEGIFICATIGN forming part of Letters Patent No. 337,413, dated March 9. 1886.

Application filed June 24,1885. Serial No. 169,638. (No model.)

T at whom it may concern.-

Be it known that I, JACOB M. MARCH, of Pennsylvania, residing at No. 1522 Sixteenth street northwest, W'ashington, District of Co- 1umbia,have invented a new and original Iniproveinentin Combined Inside Trunk-Braces, of which the following is aspecification, refer ence being had to the accompanying drawings, forming a part thereof, and to Letters Patent granted me for an improvement in inside trunk braces, No. 315,046, and dated April 7, 1885.

The object of thisiniprovement is to prevent interior expansion of'the trunk or structure,

to add additional strength to the hinged brace referred to in the said patent, and to enable the said brace to be the more readily adjusted and detached by the several bearings being made in form convex and concave.

Figure 1 represents a portion of a trunk or structure with corner-sockets and side bearings attached; Fig. 2, the hinged brace as it appears when adjusted, sections and parts thereof; Fig. 3, a section of brace with attachments thereto; Fig. 4, modifications of side bearings or clasps in front, back, and edge views, and Fig. 5 combined corner braces and sockets.

Section (1, Fig. 2, presents a portion of the hinged brace about being inserted into side clasps or bearings attached to the walls of the structure, as shown more plainly at b. The

clasp c in group Fig. 2 is intended to' be attached by means of screws or other fastenings to the under crossbar, (1, same group, either on top or underneath the surface of said bar, and consists of a vertical rear wall having an upper and lower horizontal lip. These lips are intended to overlap and engage the edges of pivoted bar 0, thereby fastening in position the hinged brace from side to side, section 9 being an edge view of the foregoing described clasp. I

The letter It, Fig. 3, represents a portion 01" the under cross bar. d, Fig. 2, and of the convex edge of hinged brace, to which is attached the plate h by means of screws, nails, or other fastenings in holes provided therefor, which has on its frontal edge or face an upwardlyturned tongue and shoulder, r. This plate may be fastened either on the top or on the bottom of the convex edge of brace shown in Fig. 2. Parts 1' and is, same figure, are edge views of the said plate somewhat modified. Section I, same figure, isa similar device to those last above described, and provided in like manner with an upwardly-turned tongue, but designed to be affixed to the convex sur face of the hinged brace immediately upon the face of said surface.

Either of these plates may be used to prevent interior expansion of the trunk or structure by intersecting or by being introduced into the vertically-inclined aperture provided with the retaining point or' shoulder in side clasps or bearings shown in Fig. 4.

The tongue-plate h and the clasp a may be made either separate or in one piece of material, and attached to bar (I either at top or on the bottom. for the purposes hereinbefore described. The front view of plate or clasp m of same group is essentially the same, and intended for like use, as shown in Letters Pat cut above referred to, except that the walls thereof are concaved to permit the edges of the, hinged brace to rotate therein. These concaved portions are also provided with the openings atp p for the insertion therein of the" tongue 1', Fig. 3, above described. The opening may be made either at the middle of the concaved portion in section running length wise, or near the top thereof, as shown; This opening, moreover, is made to slope upward, so as to form a retaining point or shoulder, as shown at s, Fig. 2, back of which the tongue 1, Fig. 8, clasps when the hinged brace is adjusted.

The modifications tand a, Fig. 4, are side clasps or bearings concaved, asis the modification shown at m, and constructed of one continuous oval or round frame of metal, but

whose rear walls are a fiat vertical surface at is shown at the points 3 3 The modification z, in the group Fig. .4

shows a three-quarter view of the side bear- 1 ing or clasp and the ilpWardly-inclined opening atp, Fig. 4.

In Fig. 5, A, B, and C are representations of the metallic corner sockets and braces described in Letters Patent before referred to, A being identical therewith, except that the interior part between the horizontal upper and lower shelves forms one continuous concave surface, in which the corners of hinged brace, Fig. 2, rotate, socket B differing from the last-described corner-brace by having upper and lower horizontal shelves of equal projection, but in all other respects like that of A, and used for same purpose, while corner brace or socket '0 is a plain piece of metal, whose surfaces are flat, having two arms intersecting and extending at right angles. Against the face of one of these angles is fastened, by means of screws, rivets, or other proper and secure devices, the concaved portion of section m, Fig. l, which, as here shown, extend the whole length of the side walls of the trunk or structure, or only a portion of the length thereof, on a horizontal line, to be used for the purpose of engaging the convex edge surfaces of the combined brace when it is adjusted. This concaved surfacev D is provided with an aperture identical with that at 1), Fig. 4, having a retaining-shoulder for the purpose of receivingthe upwardlyturued tongue at r, Fig. 3. The corner-brace C may be used either in combination with the extended concaved surface D, or employed asa separate and distinct corner-brace. This construction is shown within the trunk or structure at j, Fig. 1.

The several side clasps or bearings and the corner braces or sockets may be placed vertically at any given distances apart and attached to the trunk or structure separately, or, if desired, may be molded in groups and fastened in the manner and for the purposes set forth in Letters Patent dated April 7, 1885, No. 315,046.

The openings between the frame constituting the hinged brace is intended, if necessary, to be filled with surfaces of wire-netting, wire-cloth, webbing, wooden slats, or other suitable material.

If found necessary and desirable, all parts of the foregoingdescribed braces having concaved surfaces may be transformed to convex surfaces, and such parts thereof as are convex may be made concave in form. The same appliances, however, for preventing interior expansion shall be used, though located on reversed surfaces. At present, however, it appears that the method of construction shown by the accompanying drawings and described in this specification seems to be the better.

What I claim is 1. The combination, with the hinged brace provided with theshank having an upwardlyturned tongue, the keeper H, and clasp O, of a socket attached to the sides of the trunk and provided with the aperture or socket having the retainingshoulder, substantially as set forth, and for the purposes described.

2. In a trunk, a side bearing for the brace, provided with the aperture or socket having an upwardly'sloping retaining-shoulder, substantially as described, and for the purposes set forth.

3. The combination of a hinged brace provided with the shank having an upwardlyinclined tongue, and a concaved side socket or bearing having an upwardly-sloping retaining-shoulder, substantially as set forth,and for the purposes described.

4. In a trunk, the combination corner-brace and bearing provided with the concaved surfaces for the hinged brace, as set forth, and for the purposes herein described.

5. The combination of the hinged brace with the corner-braces, having concaved bearing-surfaces for the said hinged brace, all substantially as set forth, and for the purposes described.

6. The right-angle brace, in combination with an independent concaved side bearing extending the length of the trunk, and provided with the aperture or socket having the retaining-shoulder, substantially as set forth, and for the purposs described.

7. The combination ofthehinged brace with the right-angle braces and the i udependent side bearings extending the length'of the trunk, and provided with the aperture or socket having the retaining-shoulder, substantially as set forth, and for the purposes described.

8. A trunk provided with inside cornerbraces having the concaved bearings, the longitudinaland concaved side bearings or clasps provided with apertures or sockets having the retaining-shoulders, and the hinged brace provided with the upwardly-turned tongue,

substantially as described, the clasp c, and the over-bar H, substantially as described, and for the purposes set forth. J M. MARCH.
